3.3.5 Mesh & BCs Tab

The domain is defined and the mesh is created using this tab.

• If that is not already the case, select the Mesh & BCs tab at the top of the TransATUI
window

Domain & Grid
In this section the domain and the computational grid for the simulation will be defined.

• Select the Domain & Grid tab in the panel on the left-hand side

• In the Domain section, set the domain boundaries as follows

X min : 0.0
X max: 8.8
Y min : 0.0
Y max: 0.04
Z min : 0.0
Z max: 0.01

• Set the following parameters to define the number of cells in the domain and the refinement
zones.
Nx: 301 , Cell Ratio : 1.10 , Maximal Ratio : 4.0
Ny: 35 , Cell Ratio : 1.10 , Maximal Ratio : 4.0
Nz : 2 , Cell Ratio : 1.10 , Maximal Ratio : 4.0

Blocks
The grid will now be decomposed into 4 blocks, so that the simulation can be run on up to 4
processors.

• Select Blocks to define the multi-block options

• Click to cut the domain into several computational blocks

• Set the number of blocks in the X direction to 4. Leave the number of the blocks in the
Y direction to 1

• Click

The domain is automatically cut into 4 blocks of equivalent number of cells.
